Application filed A rils, 1917. Seria1No.'159,f162 1 l To all whom it may concern Be it known that I, J 01 m A. LINSTROM, a citizen of the United btates, residing at Bancroft, in the county of Cuming and State of Nebraska, have invented certain new and useful Improvements in Latches and Latch- Operating Mechanism, of which the following is a specification.

My invention relates to latches and a manpally operable operating mechanism there- The primary object of my present invention is to provide a latch which will effectively retain the door or gate in closed position and which may be readily operated from either side of the door or gate to open the same.

It is another object of my invention to provide a latch and latch operating means which may be easily and readily applied to any gate or door without materially changing the construction.

A further object of my present invention is to provide a latch and mechanism for operating the same which consists of few operating parts, is inexpensive to manufacture, the parts which may be assembled and disassembled and which will be durable and efficient in operation.

The above general objects and others will become apparent in the following description and the inventive idea claimed therein and the invention illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a gate or door having my improved latch and operating mechanism mounted thereon.

Fig. 2 is a horizontal sectional view taken on line 2-2 of Fig. 1.

Fig. 3 is a vertical sectional view taken on line 22 of Fig. 1, and

Fig. 4 is a transverse horizontal view taken on line 4-4 of Fig. l and showing the sliding bolt in elevation.

Referring to the drawing in which similar reference numerals designate like and corresponding parts throughout all of the views, the numeral 5 designates a gate or door of any desired construction which is provided with an opening 5 and has straps or keepers 7 mounted thereon. A like strap or keeper 8 is mounted on the side of a stationary support 9.

Slidably mounted through the keepers 7 Specification of Letters Patent,

and 8 is abolt 1 0 which has one-end thereof bent at-rightangles as atill which llm tsthe movement of this bar in one direction.-

.- mi itate 81; "1.9.

tending throughthe openingfi and rotatably mounted therein is the ri'glitrangularly disposed end ofthc operating rod orhan'dlel3 formed with an eyel lat its-lower end. This right angularly extending end of the rod 13 has nuts 15 .threaded'thereon which are engaged with the opposite faces of the gate. This end of the rod 15 extends outwardly for a distance and has connected thereto an operating rod 16 by means of a set screw 17. The lower end of the rod 16 is provided with a ring or eye similar to the ring or eye 14 of the rod 13.

Connected with the eye 21 carried by the rod 13 is one end of an expansible spring 32 which has its opposite end connected with the eye 21 secured to the strap 7 at the forward end of the gate 5. The normal tendency of this spring 22 is to urge the bolt 10 toward the keeper 8 and retain the same in locked engagement with this keeper.

Mounted on the gate 5 at opposite sides thereof are hasps 23 which are of the usual construction. Locks 24; are adapted to be engaged with these hasps and the eyes formed upon the lower ends of the operating rods or handles 13 and 16.

It will be seen that when it is desired to open the gate from either side thereof, either of the rods or handles 13 and 16 are moved toward the rear end of the gate 5 which will move the link 19 away from the keeper 8 which causes the bolt to be retracted from this keeper 8. Upon releasing the handle or rods 13 and 16 the latch will assume the full line position shown in Fig. 1 owing to action of the coil springs 22.

It will be noted that I have provided a latch and latch operating mechanism that can be looked upon either side of the gate, and when unlocked can be opened from either side. It will also be noted that my improved latch and latch operating mechanism can be operated with little effort and is one which is simple, efficient and durable in use.

This disclosure is merely for the purpose of illustration only and it is to be understood that the inventive idea can be carried out in constructions other than the one herein specified. I do not limit myself to the exact details herein stated but my limitations of modifications are only limited by the herewith appended claims.

What is claimed is g 1. The combination with a door of a horizontally sliding bolt, operating levers arranged for swinging movement upon opposite sides of the door and connected together at one end, a link connecting the intermedi ate portion of said bolt with the intermediate portion of one of said levers, a spring engaging the bolt and normally 'urging the same to aprojected position, and means engageable with the free ends of said levers to retain the levers against swinging movement in a direction to retract said bolt.

'2. The combination with a door, of a sliding bolt, an operating lever mounted for swinging movement on opposite sides of said door and pivotally connected thereto above said bolt, a link connected at one end to said bolt and at its opposite end to one of the levers below the pivot point thereof, staples extending at right angles from opposite sides of said door below said bolt, eyes formed on the free ends of said levers and arranged to be alined with said staples, and fastening means insertible through said eyes and staples to lock the bolt in a projected position.

In testimony whereof I aflix my signature in presence of two witnesses.
